Motor controllers must be marked with?

Motor controllers must be marked externally with multiple things such as the manufacturer's name or some form of ID, the number of phases, the voltage, the current, the ID of the motor being controlled, current rating or trip setting, and the kW which is the horsepower.


What is a braking resistor?

A braking resistor is used in motion systems where a motor in controlled by a drive. Typically, these are high-speed servomotors controlled by a servodrive. When accelerating, electrical energy is converted to a mechanical force to move a mass. When decelerating, that kinetic energy is converted (via the motor) back into electrical energy, and must go somewhere. To brake quick enough, the energy must be dumped into a power resistor, to be dissipated as heat. Read more at the link provided below.


What is potential barrier in PN junction?

Whenever two dissimilar conductors touch a "potential barrier" forms. All conductive materials have a voltage above zero that an electron must have to enter the material. In true conductors, this voltage is very low. In semiconductors, it can vary, but is usually in the 0.25 to 6.8 Volt range. In insulators, it can be very, very high. When two semiconductors or a metal and a semiconductor touch the difference is polarity sensitive. The higher the "band gap", the voltage that must be overcome to enter the "conduction band", the higher the voltage drop in the forward bias direction. Think of the "band gap", or potential barrier, as being like a curb on a road and sidewalk. It's easy to ride a bike off the sidewalk over the curb onto the road, but not so easy the other way.


What is unidirectional current controller device?

A unidirectional current controller device is a type of electrical on/off switch. In order for an item to work that is plugged into a particular outlet, the switch must be in the on position. It is like having lamps plugged into outlets that are controlled by only one switch.

How do you get past the barrier on mythology poptropica?

To get past the barrier in Mythology Island on Poptropica, you need to retrieve the Golden Apple from the Garden of the Hesperides. First, you must find the nymphs and convince them to let you in by completing a task for them. Once you have the Golden Apple, return to the barrier and use it to gain access to the next area. This will allow you to continue your quest on the island.

Does A workplace must have an MSDS for all controlled products used in the work environment?

Yes, a workplace must have an MSDS (Material Safety Data Sheet) for all controlled products used in the work environment in order to provide information on the potential hazards of the products and how to work safely with them. Having MSDSs readily available ensures that employees have access to important safety information.
